Hagos Mehreteab has been a founder, a CTO, a recruiter, and now he combines all those skills into one as "Head of Organizational Engineering" at Codecademy.  Basically, as it relates to the people side of the business, he turns all of the whack-a-mole type things that come up at a startup into measurable, repeatable processes.  When you think of it that way, it makes sense that you'd put someone technical in that role.  Even when it comes to people development and soft skills, if you're going to do something at scale, you're going to have to make it scalable, and that's what this former engineer has done at Appnexus and is now up to at Codecademy.
